Applied Materials Falls 4%, Lam Research and Teradyne Sink 5%: What’s Prompting the Selloff in Chip Equipment Stocks?
Applied Materials (AMAT) fell 4% to $494.82, while Lam Research (LRCX) and Teradyne (TER) dropped 5% amid concerns over AI infrastructure spending. The selloff comes despite a decline in long-end Treasury yields, which typically benefits growth stocks. Anthropic and OpenAI reported lower-than-expected revenue run rates, fueling doubts about AI capex durability. The iShares Semiconductor ETF (SOXX) is up 77% YTD, but individual equipment stocks have seen larger gains.
How this was made

The 30-second read
Why it matters
The price declines suggest investors are re‑evaluating the sustainability of AI‑driven spending, which could affect future earnings expectations for equipment makers.
Market read
Sector‑wide equipment selloff highlights potential AI capex slowdown, impacting related equities.
What to watch
Recent Treasury yield declines could eventually support growth stocks if AI spending stabilises.
Background
The article discusses a sector‑wide pullback in chip equipment stocks amid doubts about AI capex durability.
Ticker impact
Applied Materials shares fell 4% in midday trading, extending a selloff in chip equipment stocks.
Potential further downside if AI spending doubts persist.
The move reflects broader sector repricing rather than a company-specific catalyst.
Lam Research dropped 5% in the same session, the deepest single‑day decline among peers.
Likely to stay pressured unless new AI spending guidance emerges.
Peer‑group selloff driven by sector‑wide concerns.
KLA Corporation fell 4% as part of the equipment‑stock pullback.
May see modest further losses pending sector sentiment.
No firm‑specific news; price move is reactionary.
Teradyne slid 5% despite a 109% YTD gain, reflecting the sector unwind.
Potential for continued volatility as investors reassess AI spending.
Price action driven by sector dynamics, not new company data.
Market effects
AI equipment exposure may be re‑priced lower across the semiconductor supply chain.
U.S. equity indices showed modest gains, masking equipment weakness.
Potential ripple effect on overseas equipment makers and AI‑related capex forecasts.
Counterpoint
If AI capex proves resilient, the selloff could be an overreaction offering buying opportunities.
